Phenotrans is a pharmaceutical company responsible for manufacturing the controversial, anti-zombification drug known as Zombrex. They have been criticized by numerous parties, including C.U.R.E. for their exploitative approaches towards development of anti-zombification medication. There are rumors that Phenotrans purposefully withholds the creation of a cure in order to extract money from its customer base.

Despite all the suspicion and misgivings about The Phenotrans Corporation, many Americans don't question their methods because of the growing demand and dependence for Zombrex in the nation.
